Abstract (en)
[origin: EP0282044A2] A scanning exposure device comprises a projection lens, a photosensitive member disposed beneath the projection lens, two movable mirrors disposed with their reflecting surfaces facing upward and having asymmetrical inclinations relative to each other, and a stationary mirror disposed with its reflecting surface facing downward to form an optical path together with the movable mirrors. The two movable mirrors are driven for scanning movements so as to expose a picture image from the projection lens on the photosensitive member through a slit. Thus, an optical path is established in which the light beam projected from the projection lens located at a higher position is guided toward the photosensitive member located at a lower position.
